That particular unit says it employs hiccup mode protection on current overload.

This one does, for ~35$

Just yesterday it held 40 amps for an hour straight charging a fairly healthy starting battery that had been depleted to 9.23v. 14 hours after removal from meanwell, battery is at 13.14v. It was interesting to watch the inline watt meter during the first few minutes. It only wanted 23 amps at first, and voltage instantly rose to 14.45, but a minute or 2 later voltage had dropped to 12.93v and the battery was gobbling up 40 amps.
